Active Patterns
Active Pattern |
Description |
|---|---|
AndAlso : Expr -> (Expr * Expr) option |
Recognizes expressions of the form a && b. |
Applications : Expr -> (Expr * Expr list list) option |
Recognizes expressions that represent the application of a (possibly curried or tupled) first class function value. |
Bool : Expr -> bool option |
Recognizes constant Boolean expressions. |
Byte : Expr -> byte option |
Recognizes constant byte expressions. |
Char : Expr -> char option |
Recognizes constant Unicode character expressions. |
Double : Expr -> float option |
Recognizes constant 64-bit floating point number expressions. |
Int16 : Expr -> int16 option |
Recognizes constant int16 expressions. |
Int32 : Expr -> int32 option |
Recognizes constant int32 expressions. |
Int64 : Expr -> int64 option |
Recognizes constant int64 expressions. |
Lambdas : Expr -> (Var list list * Expr) option |
Recognizes expressions that represent a (possibly curried or tupled) first class function value. |
MethodWithReflectedDefinition : MethodBase -> Expr option |
Recognizes methods that have an associated ReflectedDefinition. |
OrElse : Expr -> (Expr * Expr) option |
Recognizes expressions of the form a || b. |
PropertyGetterWithReflectedDefinition : PropertyInfo -> Expr option |
Recognizes property getters or values in modules that have an associated ReflectedDefinition. |
PropertySetterWithReflectedDefinition : PropertyInfo -> Expr option |
Recognizes property setters that have an associated ReflectedDefinition. |
SByte : Expr -> sbyte option |
Recognizes constant signed byte expressions. |
Single : Expr -> single option |
Recognizes constant 32-bit floating point number expressions. |
SpecificCall : Expr -> Expr -> (Expr option * Type list * Expr list) option |
A parameterized active pattern to recognize calls to a specified function or method. The returned elements are the optional target object (present if the target is an instance method), the generic type instantiation (non-empty if the target is a generic instantiation), and the arguments to the function or method. |
String : Expr -> string option |
Recognizes constant string expressions. |
UInt16 : Expr -> uint16 option |
Recognizes constant unsigned int16 expressions. |
UInt32 : Expr -> uint32 option |
Recognizes constant unsigned int32 expressions. |
UInt64 : Expr -> uint64 option |
Recognizes constant unsigned int64 expressions. |
Unit : Expr -> unit option |
Recognizes () constant expressions. |
